Most bitmap file storage formats don’t have a way to store the spatial reference information in the same file as the bitmap image. With most vector formats (DXF, SHP, etc.), the Coordinate System option is on the Scaling tab. The Coordinate System option is not available for all file formats. To export only some of the objects to the desired coordinate system, select the objects first and check the Export selected objects only option on the Export dialog. This can be changed to any of the Map coordinate systems in the list and all objects will be exported to this coordinate system. If more than one Map object is selected, the Coordinate System is set to Paper space (page units). If a single image is selected in the plot window, the coordinate system for the image is used for the Coordinate System. If a single Map is selected in the plot window, the map coordinate system is used for the Coordinate System. All objects are exported in the selected Coordinate System. To select the appropriate map, click on the existing map name and select the desired map from the list. Available options are Paper space (page units), all map frame names in the Surfer file, and any coordinate system for each image in the Surfer file. Next to Coordinate System, select the appropriate coordinate system to use when exporting the file. The Spatial References page allows you to choose how to save the projection, datum, and georeference information. If the map that you are exporting has a coordinate system defined, the Spatial References tab will appear in the Export Options dialog. Some applications associate spatial reference information (such as projection, datum, and georeference parameters) with files, to link the file to a specific region of the Earth’s surface.
